Agree this would be awsome to include, heck if I get time I could even contribute if someones starting it. There's one problem though: you'll need a rather plausible scenario for this as Sweden as a neutral country would not declare war or attack an other country (unless as a part of an european battle group)
So it would most certainly be an other country to attack Sweden (like Russia), which in the other hand would be awsome cause you would like fighting in a snow landscape and such.

But heck, if someone gets up a plausible story then I'd contribute with all I could.
